Suspended substance suction head

Abstract

The invention discloses a water surface suspended matter suction head which is placed on a water surface and comprises a suction head main body and an air release valve. The suction head main body comprises a top plate, an inner barrel, an outer barrel, an outer barrel bottom and outlet openings; the inner barrel is placed vertically; the top plate is arranged on the top surface of the inner barrel; the outer barrel is arranged on an outer ring of the inner barrel; the outer barrel and the inner barrel are coaxial; the top surface of the outer barrel is lower than the top plate; the outer barrel bottom is arranged between the bottom surface of the outer barrel and the bottom surface of the inner barrel; the outer barrel bottom is of a ring shape; the lower surface of the outer barrel bottom is provided with a plurality of outlet openings downwards; an inner barrel region with a downward opening is constructed by the top plate and the inner barrel; a suction region with an upward opening is constructed by the inner barrel, the outer barrel and the outer barrel bottom; the outer barrel is provided with a plurality of weir ports; the weir ports are positioned at the top of the lateralsurface of the outer barrel; the weir ports are circumferentially and uniformly distributed along the axis of the outer barrel; the weir ports are one-section grooves; both ends of the weir ports arerespectively positioned on the outer wall face and the inner wall face of the outer barrel; the air release valve is arranged on the top plate; and the air release valve is connected with the inner barrel region and the atmosphere.

Description

technical field [0001] The invention relates to the field of lake water treatment, in particular to a suction head for suspended matter on the water surface. Background technique [0002] Suspended matter refers to some foreign matter on the water surface, such as cyanobacteria, green algae, catkins, water weed residue, etc., cyanobacteria can multiply in some nutrient-rich water bodies, forming a layer of blue-green and fishy-smelling floating foam on the water surface. Commonly known as "Water Bloom", in recent years, frequent cyanobacteria outbreaks in inland lakes have seriously affected people's lives. Therefore, the prevention and control of suspended solids has become a module in the field of water governance. The treatment method of suspended solids in large lakes is generally to salvage the suspended solids, to prepare organic fertilizers after crushing, concentrating and dehydrating, to generate biogas by fermentation, and to produce biodiesel, etc. [0003] The ...

Problems solved by technology

[0003] The existing suspended solids salvage method adopts manual or pump suction, which is labor-intensive and low in efficiency, while the existing pump-suction salvage will suck a large amount of water at the same time, not only the pump has a large power, Moreover, the follow-up of pumping needs to be filtered, the process is cumbersome, the energy consumption is large, and the efficiency is low.
